Products, side by side
Algorithmic pairing — assembled from recorded fields, not hand-checked
Fiddler AI
Platform
AI observability platform: evaluation, monitoring and real-time guardrails for ML models and generative AI/agentic applications in production.
Toloka
Platform
An independent evaluation platform that ranks frontier LLMs on agentic tool-use tasks using private, non-contaminated benchmarks across industry domains, scored on a pass^5 reliability metric, with the underlying RL Gyms and evaluation datasets available to license.
A self-serve service that lowers per-request inference cost through two tools - fine-tuning LoRA adapters on frozen Qwen3 base models to replace a frontier API on a narrow task, and prompt gisting that compresses long instruction prefixes into learned tokens.
No counterpart
Fiddler AI sells these in a stack layer with no product recorded for Toloka yet — nothing on the other side to compare them against.
Application
Governance module within the Fiddler AI Control Plane providing model inventories, policy enforcement and audit-ready reporting for regulatory compliance (e.g. EU AI Act) across an organization's AI systems.
Tracing and monitoring module for multi-step agent workflows within the Fiddler AI Control Plane, tracking tool calls, reasoning steps and failures across an agent's execution.
Ongoing automated evaluation module within the Fiddler AI Control Plane that re-scores production LLM/agent outputs against quality and safety metrics over time, not just at launch.
Runtime safety layer within the Fiddler AI Control Plane that screens LLM/agent inputs and outputs for hallucination, toxicity, PII and jailbreak attempts before they reach users.
Developer tool
Source-available library for red-teaming and robustness testing of LLMs, run independently of the hosted Fiddler platform. Fiddler's own page calls it "open-source"; its repository's actual licence is the Elastic License 2.0, which is not an OSI-approved open-source licence (it restricts offering the software as a competing hosted service), so it is recorded here by its real terms rather than the vendor's label.
Toloka sells these in a stack layer with no product recorded for Fiddler AI yet — nothing on the other side to compare them against.
AI agent
A hybrid AI-plus-human agent that takes a delegated task - research, data analysis, copywriting, design or development - has AI do the first pass, then routes it to one of 10,000+ vetted experts for verification and multi-layer QA, returning results in 2-24 hours.
Data service
Toloka's catalogue of ready-made training datasets sold outright — three named at the time of writing (Tau-bench Dataset Extension, University-level Math Reasoning, Multimodal Conversations) — as distinct from the custom data work its Platform sells.
Human-in-the-loop data programs -- demonstrations, annotation and evaluation -- for training robotics and physical AI systems.
A self-serve platform where an AI agent turns a described data goal into a full human-annotation pipeline - RLHF and preference data, data collection, instruction tuning, model evaluation, synthetic-data validation and content-moderation QA - with LLM-based quality checks on the output.
